OK, I reloaded a batch of 230Gr 45 ACP FMJ RN that fail the plunk test. I coated the round in a dry erase marker and plunked and turned the round. The round does not turn after plunked. It does fully seat where it should. It just does not turn in the barrel/chamber.
I took out a factory round Winchester White box 230 grain FMJ to compare. The factory round passes the plunk test. The reloaded round is the exact same COAL as the factory round at 1.260.
I took my caliper to the rounds and at the top of the case mouth, the bullet is .437 for the factory round and my reloaded round is .450 This is right where the marker trick is showing me the problem. The rounds chamber and extract fine.
Is this a reloading issue or a bullet issue? I guess I am asking is there something I can do to fix this or is it simply the bullet design? I can seat it a little further in I suppose. You can see the missing strip of black marker where it rubbed off after turning in the barrel.
